If you do use hard RAID, make sure you back up the card's config and keep the backup in a safe place.
This is probably a good idea anyway, but I'd like to point out that most hardware raid cards (and linux software raid) keeps the array config on the array members themselves. That is, you can typically swap the raid-controller, reboot and see your old arrays.
That is *definitely* the case for 3Ware cards.
